Application April 16, 1949,.Serial No. 88,018 In the NetherlandsAprilB, 1948 .9 Claims.

Theinventionrelates to a screen printing table, to :be used :for the. execution of s-oca1l,ed screen brintingjf or fabrics.

j-In the screen printingprocess, lengths of fabric are laid on very long tables, which might have a length of-90-100 In, On the fabric-are laid'stencils through which dye is applied to the fabric.

Anunderlayer, e. g.,of feltand rubber, generally fabric glued on rubber, is provided on the tables. The drying. of the dyed fabric is a problem in such screen printing processes.

Screen printing tables have already been constructed-in theform of long, flat metallic boxes. in which heating tubes are provided, andthe heat of the heating tubesmust betransferred to the screen-.topuby means of air conduction, which results in great heat losses. Moreoverthe metal plates forming the screen top caneasily expand and/or: deform which is very undesirable.

The. objects ofthepresent invention are, amon others, :to overcome the above difiiculties- A-ccording'to the invention, the screen top consists of massive material,v preferably concrete, in which at least one heating tube, preferably having azig-zag shape, is located in such a way that the material of the screen top bears against the outer surface of the heating tube and surrounds the same.

.Inthis way a-veryeili-cientheating of the screen top is obtained.

in order to enable the necessary expansion :to take place, the screen top .is preferablyplaced on rollers, whichyrest on the upper sides of support- .ing ,walls.

If the screen topconsi-sts of concrete, the heating tube, or tubes, are embedded in -the concrete. The screen top can also consist of other material, as .e. g. syntheticmaterials. Preferably material with a small coefiicient of expansion will-be'used to keep contraction and expansion down to a min- A gscreen'top in such, a way that the edgesofthe screentop, and also the edges of the fabric, are well heated.

The heating tube, or tubes, serve also as a reinforcement 'for thelong tables.

As screen printing tables are generally very combinat on,

long, it is advisable to provide morethanione' heating tube. If the heating medium should" only pass through one long zigzag tube,1-.t-oo much heat would be absorbed atan end of the table The heating of the tablecan proceedmoreuni formly by simultaneously supplying theheating medium at several places alongthe length of the heating tube in thetable. g

The problem of heating and drying canibe solved in a very efiicient way with-the. apparatus according to the invention, when the screentop provided with the heating tubes is ,placedonrollers.

The invention is shownmore precisely inlthe accompanying drawing, in which'an embodiment is illustrated;

Fig. 1 shows schematically a cross-section through thescreen top; I

Fig. 2 shows a vertical section through the screen top and Fig. 3 shows a transversesection throughthe tableon an enlarged scale.

A heating tube 2 is locatedin the screen top .As appears from Fig. 1 the heating tub-e is=c0n euently a uniform heating is easily iobtained',,and the-temperature can also be. maintained' at azpredeterminedilevel.

As appears from Fig. ,2, the screen top is LSQP, ported byrollers l, which are placed oil-the bear ing walls 43, e. g. on T-shaped supports '9 inthis way spaces 1!] are formedbetween thejlscreenitop andthe bearing well. From Fig. 3.,.ii-t;;is' apparent that the tube 2 canrest on supports ll, which are embedded in 'the concrete underlayer .of the table.
